aZZ whom/t may concer/n.:

Beit hereby known that I, FRED K. FIN- NEMAN, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of `Oregon (whose post-office address is 469 Clay Street), have invented a new and useful Saw-Clamp Guard, of which the. following is a speciii cation.

This invention relates'generally to the art of tiling saws, and particularly to the type of saw clamp in which the clamp passes around the toothed edge of the saw instead of around the back of the saw as is commonly the case.

The first obj ect of this invention is to provide an exceedingly simple and efficient saw guard by means of which the saw teeth will be prevented from coming in contact with the clamp when shifting the position of the saw.

rlhe second object is to render unnecessary the extreme care which the filer must employ when shifting his saw, thereby reduc ing the time of filing and enabling him to direct his attention to the object which he is trying to accomplish, namely the sharpening of the saw.

The third object is to prevent any of the saw teeth from becoming dulled by contact with the saw clamp, or, if resharpened, shorter than the adjacent teeth.

rllie fourth ob `ect is to so construct the device that it may be readily applied to the saw clamp, or replaced if worn out, without the aid of a special tool not ordinarilyfound in a carpenters lrit, and at the same time to render the device capable of being so securely fastened that it will not readily become separated from the clamp.

These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which:

- Figure 1 is a plan of the saw clamp showing my device attached. Figure 2 is a front elevation of the device as shown in Figure 1. Figure 3 is a side elevation of the device at a somewhat larger scale showing same attached to a table top or bench. Figure -lis a vertical section taken along the line 4-1l in Figure 3. Figure 5 is a front elevation of the device itself, of which Figure 6 is an end elevation and Figure 7 is a plan.

Similar numbers of reference refer to the same parts throughout the several views.

I YReferring in vdetail to tliedrawing, there 1s illustrated a type of saw clamp in which the clamp passes around the teeth 10 of a saw 11. The clamp itself consists of a longitudinal angle member 12 and a flat bar 13 which are tied together at their ends by the side frames 14 having channel shaped cross sections. On the member 12 is placed a rubber strip 15 which is secured by means of a metal strip 16 which is held in place by the screws 17.

Between the downeturned ends 18 of the side frames 14 there is pivotally mounted an eccentric bar 19 provided with a handle 20. A bench clamp arm 21 is attached to the angle iron 12 by means of a rivet 22 and is provided at its lowermost end with a clamping screw 23 having a handle 24 and a woodengaging end 25.

Turning now to the guard itself, which is plainly illustrated in Figures 5, 6 and 7 it 'will be seen to consist ofk a somewhatrectangular block 26, preferably of rubber, and having a somewhat rounded edge 27, and is provided with a thin strip of metal 28 which projects fromeach end of the member 26. The guards 26 are of such shape and size as to fit snugly into the openings between the side portions of the frames 14, and the strips 28 are suiiiciently long to permit their being clamped inwardly and downwardly against the upper sides of the frames 14, as shown in Figure 4f.

rl `he operation of the device is as follows: The saw 11 is placed against the angle iron 12 and the eccentric bar 19 is rotated in a manner to securely clamp the saw in place in the position for filing. When it is desired to move the saw it is not necessary to exert any special care to see that the teeth 10 do not become dulled by contact with metal, since the only object which they can touch is the und-er side of the guards 26.

It will be'understood, of course, that theV exact shape and size, as wellas the kinds of hardware for attaching the guards 26 may be varied to suit the particular kind of side frame 111 with which they are employed: it being' borne in mind, however, that the guards above described are necessary only with the type of saw clamp in which the clamp members pass around the toothed edge of the saw as above suggested.

While the guard members have been referred to as being made of rubber, it must be understood that these may also be made of any other material such as Wood or conljecting from each end thereof, said rnetal be- 10 position which is sufficiently soft to prevent ing parallel with the straight edge of said the teeth from being dulled when coming in guard opposite said rounded edge. contact with same. 2.
